12.4 Electrical connection
12.4.1 General information
WARNING Electrocution
If the appliance is connected to an automatic charge con-
trol system, there may be voltage at terminals A1/Z1 and
A2/Z2 even if the fuses have been removed.
WARNING Electrocution
The supplied safety label in the language of the respec-
tive country must be affixed over the safety label reading
"Achtung - Fernsteuerung! (Caution – remote control!)"
on the angled panel of the mains terminal.
The electrical connection of the heating elements is made with
3/N/PE~400 V. With the single phase connection kit (accessory), a
connection with 1/N/PE~230 V is also possible.
The connection is possible with NYM. The number of power cables,
conductors and cross-sections depends on the connected load of
the appliance and the type of power connection, as well as on
special regulations from the power supply utility.
Observe the wiring diagram and output stages (see chapter "Spec-
ification").
12.4.2 Connecting the appliance
WARNING Electrocution
Ensure the earth conductor is properly connected.
WARNING Electrocution
Connection cables must not be damaged, removed or
pulled out of the appliance.
f Route the connecting cables accordingly.
Note
There must be continuous voltage at terminals L and N
on terminal strip X2.
f Apply strain relief to the power cables and connect them
according to the wiring diagram inside the appliance (on the
inside of the r.h. side panel), or according to the wiring dia-
gram in chapter "Specification".
If the angled panel located in the wiring chamber interior for
mounting the mains terminals is not easily accessible because
the side clearance is inadequate, you can pivot it forwards after
undoing the retaining screw.
12.4.3 Control without heating contactor
If a heating contactor is not installed (may be required by the
power supply utility), the function in the storage heater's PCB
can be used.
f For this, connect either the LF and N power-OFF signals or
the SH and N signals of the relevant charge control system
directly to the LF/SH and N terminals of the storage heater.
f In the configuration menu, set parameter P15 to 1 (see chap-
ter "Installation / Configuration menu").
www.stiebel-eltron.com
The heating elements in the appliance are not switched on until
the LF from the power supply utility has been enabled and the
electronic charge controller has enabled charging.
12.4.4 Appliance type plate
Note
Document the connected load and the nominal charge
duration.
f Mark the relevant boxes on the type plate.
12.5 Floorstanding installation

1 Floorstanding installation
2 Installation with floor brackets
The surface on which the appliance is installed must be level and
offer sufficient load bearing capacity. For details regarding the
appliance weight, see chapter "Specification / Data table". If in
doubt, consult a qualified structural engineer.
The appliances may be installed on any conventional floor, al-
though PVC, parquet and long- or deep-pile carpets may be af-
fected by pressure and heat. In such cases, heat-resistant support
plates must be used (to be provided on site).
The stability of the appliance must be ensured by fixing it to the
wall or floor.
Wall mounting
For wall mounting on a sufficiently load bearing wall, there is a
hole in the appliance back panel near the wiring chamber.
f Secure the appliance with a suitable screw to the wall to pre-
vent it from tipping over.
Floor mounting
Alternatively, you can secure the appliance to the floor through
four holes (Ø 9 mm) in the feet.
f Remove the air discharge grille, the front panel and the air
routing assembly (see chapter "Installation / Opening the ap-
pliance" and "Cleaning the appliance").
f Secure the appliance to the floor with suitable screws.
